iMPR-OVEMENT m ELASTIC TIRES FOR-TRACTIdN-ENGINES The Schedule referred. to inlthese Letters Patent and making part of the same To all whom it may concern:

Be it known that I, OLIVER HYDE, of'Oakland', county of Alameda, State of Galifornia, have invented Improvements in Elastic Tires for the Wheels of Traction-Engines; and I do hereby declare the following description and accompanying drawing are suificient to enable any person skilled in the art or science to which it most nearly appertains to make and use my said invention or improvements without further iiivention or experiment. a

Myimprovements in elastic'ti're's for thewheels of traction-engine's relate to that class of rubber or elastic tires which are secured around the metallic tire of the wheel in blocks or segments; and 4 First, in the employment of elastic cylindrical blocks or blocks of a polygonal figure, which I secure in succession around the metallic tire so as to form a co m pleteelastic tire for the wheel; and,

Secondly, in an improved device for securing or bi nding these blocks to the metallic tire sothat suificient play is provided for the compressionand expansion of the blocks.

lnorderfto further explain my invention, the fellowing descriptionand accompanying drawing are referred to, in which- Figure 1 is a side elevation. Figure 2 is a'perspective ,view.

Figure 3 is a cross-section, showing one of the blocks.

Figured; shows another form of the blocks. I A represents the rim .or metallic tire of any wheel.

Upon each side of these blocks 1) is cast, forged, or

otherwise securedto it, a square or other-shaped side-Y.

plate, f.

.To each end of thesc side plates, or to their con ters, as shown at fig. 4, is bolted a link, I, which extends downward at an angle, and has its opposite end bolted to the vertical rims B, at the sides.

The holes through which these'latter bolts pass are slotted, as shown at c, in order 'to allow the bolts to move back and forth as theelas'tic blocks are compressedanda'eturned totheir original position,

Byth'e above describ'ed combination and arrange-. ment of parts I am able to encircle the metallic tires oftraction-wheels with a cheap, substantial, and thoroughlyefiective elastic tire, which can readily be fitted and easily repaired in cases of necessity.
